基于WRAN技术的调制解调器及其应用研究

首先,较详细地介绍了IEEE 802.22协议的主要技术原理,并提出了基于WRAN技术的调制解调器的模型,对该类调制解调器的功能原理进行了描述,对其在不同场景中的应用进行了较深入地分析。最后,对该调制解调器的市场应用前景进行了展望。

Application Research on Modem Based on WRAN Technology

Wireless Regional Area Networks (WRAN) standard IEEE 802.22 is a broadband wireless access technology that operating in television broadcast bands, modems that based on this technology will be the most popular kind of WRAN customer premise equipment. This kind of modem can be used to deploy a regional area wirless coverage, can be used in many industry applications instead of 2G/3G backhaul and WiFi network. Under well design, this kind of modem can be used not only to provide wireless internet access service, but also to provide wired internet access service instead of traditional cable modem, so it will be a good technology for television operator to get into the competation of internet communication service.
